| Abstract: | Three kinds of fluid inclusions were studied by using micro FTIR.The results show that the gold\|forming fluids evolved chemically from simple H\-2O NaCl,H\-2O CO\-2 and H\-2O CO\-2 NaCl to complex H\-2O NaCl CO\-2 H\-2O CH\-4 and CO\-2 CH\-4 H\-2O NaCl systems.This paper reports for the first time the presence of H\-2S and CH\-4 in the ore\|forming fluids in the Taihang Mountains,which is significant in the study of the mineralization in this area.There are three physically different fluid inclusions in the gold deposits.The existence of such different fluid inclusions in the same sample suggests that there exist three kinds of unmixed or coexistent fluids in the environments where the inclusions were trapped,and these unmixed fluids were violently variable. |
